I've owned and used this amplifier for the past 15 years and it has never, ever let me down. The toggle switches for the tone control and tape select are getting a bit scratchy but we all know that's expected in a a 35 year old amplifier. It's built like a tank and can handle being dropped. I know because mine was dropped as it has one corner bent! Great sound, can even handle floor monitors in live band situation at halfway volume! looks awesome too.

Bigger brother of the KA-305 base line integrated with
beefed up power amp and features and a nice faceplate
design with vu-meters. Single opamp phono pre
based on a HA1457 chip. Line amp is a NJM4558D.
Simple but good power amp. Lots of cheap coupling
caps in the signal path. Overall a decent amp that was
expensive back then and mostly is now used. Better look
for alternatives.
